Comments: Large deletion of about 285 kb in size, extending from the WASH4P gene (telomeric region) in 5’ to a part of the AXIN1 gene in 3’. Removes the entire WASH4P gene, the α-globin gene cluster, and exons 5 to 10 of the AXIN1 gene. Found together with the -α3.7 deletion in trans in a proband with Hb H disease. The proband presented with scoliosis, likely a consequence of the genetic defect in AXIN1. The deletion associated with an α0-thalassemia phenotype and not the ATR-16 syndrome. Mother was heterozygous for the deletion.
